11 Δεκ 2017 · CRISPR/Cas9 is already being used by scientists to create genetically modified crops and animals. In China, scientists have used CRISPR to create genetically modified low-fat pigs . Many believe that CRISPR could be the key to finally bringing extinct species of animals back to life.
10 Αυγ 2022 · The animals are important earth engineers. By dispersing seeds and nutrients while digging up tonnes of soil every year, they improve habitats for other species, New Scientist explains. The brush-tailed bettong, or woylie, an endangered mammal, has been reintroduced to Australia.
31 Οκτ 2014 · Today, many zoos promote the protection of biodiversity as a significant part of their mission. As conservation “arks” for endangered species and, increasingly, as leaders in field conservation projects such as the reintroduction of captive-born animals to the wild, they’re preparing to play an even more significant role in the effort to save species in this century.
17 Ιουν 2019 · Today, change is so fast, many of our larger animals simply don’t have time to adapt.

7 Μαρ 2019 · These animals coming back from the brink – others may become extinct before they’ve even been discovered – provide an illustration of the challenge facing those seeking to quantify the losses. In the end, the accuracy of such lists comes second to raising awareness.
10 Φεβ 2023 · This idea is the motivation for de-extinction projects: releasing resurrected animals into suitable habitats so as to increase biodiversity and restore ecosystem resilience. Assisted breeding, cloning and genome editing are species restoration methods undertaken with the goal of re-establishing the dynamic processes that produce healthy ecosystems and restore biodiversity.
